Bacteria that form in pairs are called ___

A. bacteria.
B. streptococci diplococci
C. staphylococci
D. clostridium difficile

Correct answers only please

B. streptococci diplococci

The correct answer is B. streptococci diplococci.

To arrive at this answer, we can break down the options and figure out the correct terminology by understanding the characteristic of bacteria that form in pairs.

- Option A, "bacteria," is a general term for microorganisms that include many different types and arrangements, so it is not specific enough to be the correct answer.

- Option C, "staphylococci," refers to bacteria that form clusters, not pairs. They are typically arranged in a grape-like structure.

- Option D, "clostridium difficile," is the name of a specific species of bacteria, but it does not refer to bacteria that form in pairs.

This leaves us with option B, "streptococci diplococci."

"Streptococci" refers to bacteria that are arranged in chains, and "diplococci" refers to bacteria that form pairs. So, option B correctly identifies bacteria that form in pairs.
